Answer:

C. 8 units.

Step-by-step explanation:

The maximum value of the cosine ( cos) function is 1

So, for y = 3cos(2x - 8) + 5

Maximum value is 3 *1 + 5 = 8.

y = -3cos(2x - 8) + 5 is the above graph reflected in the y axis so the maximum value is also 8.

Answer:

B. 7.94 × 10^8 miles

Step-by-step explanation:

Given that

Earth is approximately 9.3 × 107 miles from the sun.

Saturn is approximately 8.87 × 108 miles from the sun.

We need to find out how much farther is saturn from the sun than earth is

So,

Earth - Sun = 9.3 × 10^7 miles

Saturn - Sun = 8.87 × 10^8 miles

Now

= 8.87 × 10^8 - 9.3 × 10^7

= 88.7 × 10^7 - 9.3 × 10^7

= 79.4 × 10^7

= 7.94 × 10 ^8

= 794,000,000 miles

Hence, saturn is 7.94 × 10^8 miles farther from Sun than Earth is
